THREAD-GUARD AND SPINNING-RING HOIliiDER.

Application filed May 18, 1927. Serial No. 192,296.

This invention relates to ring spinning frames, and embodies certain improvements upon the combined thread guard and spinning ring holder described andclaimed in U. S. Patent No. 1,489,910, granted tome on April 8, 1924.

The invention as disclosed in said prior Letters Patent comprised a combined spinning ring holder and protecting device, the latter being applied to each ring of a spinning frame, and constructed and arranged to extend partly but not wholly around the circumference of each ring so as to guard the ring and traveler from flying lint, small particles of thread, etc., thrown off from adjacent rings. As shown in said patent, the spinning ring frame was provided at spaced intervals withopenings to receive the bobbins, with recesses surrounding said openings of a size and shape to receive the base flanges of the spinning rings while a longitudinal strip having cutout portions therein corresponding to the openings in the rail was provided with overhanging flanges of a size and shape to partly surround each ring, the flange extending in a curve about the ring for a little more than one-half the circumference of the ring, and said flange overlying, and being substantially coincident in its arc of curvature with the outside diameter of the upper flange of the ring and traveler, and furthermore was located in such proximity to the traveler as to prevent bowing of the yarn, and hold the same within a prescribed path of the traveler. Under the arrangement as shown in said prior patent the number of bobbins which could be placed upon a rail of given length was determined by the spaces due to the width or distance between the edges of the adjacent flanges of the protector, measured longitudinally of the ring rail, as it is not practical to locate adjacent rings any closer together than a distance which will prevent the yarn from adjacent bobbins from contacting with each other during the spinning operation. I have discovered that with the construction as shown in my prior patent, if the flanges of the protector strip which overlie the rings in the several openings of the frame are increased in width so as to have their inner edges substantially coincident with the inner circle of the ring flange, the spacing between adjacent-rings will be increased to such an extent as to permit the use of a greater number of rings on'the same frame than would be possible under the former construction; or, will permit the use of rings of a larger diameter than formerly, without decreasing the space between adjacent'bobbin centers, or in other words, between adjacent spinning rings. Another advantage following from the foregoingis that the overhanging flange will cause the yarn to be thrown toward the center of the ring with the result that the strain upon the traveler instead of being outwardly, will be substantially equalized upon the outer and inner edges of the'upper flange of the ring. The foregoing and other advantages of the invention will be better understood from the following description, in connection with the accompanying drawings and the claims appended hereto will point out the novel features of the invention. i I

Fig. 1 is a plan view of a portionof a spinning frame, showing three rings applied thereto, and, illustrating the present invention;

Fig. 2 is a front elevation of Fig. 1; gig. 3 is a section on line 33, Fig. 1; an

Fig. 4 is a section on the line 4-4, Fig. 1. The rail 2 of a ring spinning frame is provided at suitable intervals with the usual openings 3 to receive the bobbins. As here in shown, a recess 5 is formed in the rail surrounding each opening to receive the base fiange of a spinning ring 6, which spinning ring may be as shown herein of the double flange type, the upper flange or raceway being adapted to receive the usual traveler 7. The space bet-ween the flange 8 and the bead 9 on the ring constitutes the raceway for the traveler7.

Sustained upon the rail 2, and secured thereto by screws 10, or other fastenings is a strip 16 having an appropriate number of cutout portions corresponding with the number of openings 3 on the rail above which the rings are supported. The strip is recessed at 12 to provide a clear space about each ring, the recesses being curved about the rings for more than one-half of a circle, and terminating in the openings at the front of the strip, and said recesses are provided with overhangin flanges 14 which agree in curvature with t e curvature otlthe recesses, and overhangthe rings as shown especially in Fig. 3, the edge of each flange 14 being located immediately above .-.andtlagreeingi:1in curvature with, the inner edge of the upper flange of the ring. In-myprior patent previded between the outer and inner portions of the traveler which bear upon theouter and innercdges of the ring flange. Under the present invention theyarn is thrown inwardly by-the flange 14 so as to exert a, pull Whichis substantially at the middle otthe traveler, so that the wear thereon is equalized atthe two points of coutact'betwecn the traveler and ringflange.

The inwardextension of the flange 1.4;;permits the use of larger spinningyrings and hence of :larger bobbins iwithout diminishing the necessary space between adjacent rings, which is a decided advantage, and .ina'large mill wherethousandsof spindles :are in use results in .a very decided economy by increasing the output each day, as compared with former constructions of rail. "To givea concrete example .it .has been found by experiment that where the flanges 1 1 QIGGX- tended inwardly to agree with the inner edges of the rings. a two and one-quarter inch ring may be placed on the :rail with thesame space betweenbobbinsas would be required fora/two inch ring where the-overhanging .flange 14: wasdisposed as shown in my prior patent- Assuming that the necessary-spacebetween rings is as shown insaid patent where thelflangesm18 are coincident substantially with the outer diameter ofthe ring,by reconstructing :the .rail and strip so .asto accommodate a two andlone-hal'f inch ring, a ringof such increased diameter could be used by having the flange agree with the innercircleotthering, and without altering the amount of space between adjacentirings.
